openhands cb6d6e2292 fix: LM recenter() return semantics undocumented (#570) 
Add NatSpec to recenter() documenting that the function always reverts
on failure (never silently returns false), listing all four revert
conditions, and clarifying that both true/false return values represent
a successfully-executed recenter with the value indicating price
direction (up vs down relative to previous anchor centre).

Also fix StrategyExecutor.maybeRecenter() to capture the isUp return
value from lm.recenter() and include it in the log output, making
price direction visible in backtesting replays.

KRAIKEN Onchain

Solidity contracts for the KRAIKEN protocol. Built with Foundry.

Contracts

Contract Description
Kraiken.sol ERC20 token with mint/burn controlled by LiquidityManager. VERSION=2.
LiquidityManager.sol Three-position Uniswap V3 strategy (Anchor, Discovery, Floor).
Stake.sol Harberger-tax staking with snatching auctions and discrete tax brackets.
OptimizerV3.sol UUPS upgradeable. Binary bear/bull parameter selection from staking sentiment.
VWAPTracker.sol Volume-weighted average price with directional recording and compression.

Setup

git submodule update --init --recursive
cd lib/uni-v3-lib && npm install && cd ../..
forge build
forge test

Deploy

source .env
forge script script/BaseSepoliaDeploy.sol:BaseSepoliaDeploy --slow --broadcast --verify --rpc-url ${BASE_SEPOLIA_RPC_URL}

See docs/DEPLOYMENT_RUNBOOK.md for production deployment.

Research & Analysis

The analysis/ directory contains fuzzing scripts, parameter sweep tools, and security analysis:

Key findings: critical sqrt price bug fixed, 1050-combo 4D parameter sweep completed, floor ratchet vulnerability identified. See the research report for details.

ABI Architecture

Contract ABIs flow through the stack via kraiken-lib/src/abis.ts, which imports directly from out/ (forge build artifacts). Run forge build to update ABIs across all consumers (ponder, web-app).
